Optical Properties of Multilayer Colloids
The theory of Aden and Kerker on the scattering of electromagnetic waves from two concentric spheres has been applied to the interaction of light with two-layer metallic colloids. Starting with gold nuclei 59 Å in ``diameter,'' silver layers 5 to 220 Å in thickness have been grown epitaxially. The optical absorption s…
Crystal-Field Splitting of Trivalent Thulium and Erbium J Levels in Yttrium Oxide
The optical absorption and fluorescence spectra of trivalent thulium in single crystals of yttrium oxide and the absorption spectrum of pure thulium oxide, are investigated. All the 4f12 electronic energy levels except the 1S0 level are identified. The three Slater Fk parameters and the spin—orbit parameter ζ, giving…
Anisotropy Fields in Hexagonal Ferrimagnetic Oxides by Ferrimagnetic Resonance
Room-temperature microwave ferrimagnetic resonance measurements of the large uniaxial magnetocrystalline anisotropy fields (Han) of two compositional series of hexagonal ferrimagnetic oxides are reported. Han was found to increase rapidly in the Al-substitution series (SrO·xAl2O3·(6−x)Fe2O3) from 19.3 to 53.4 kOe as x…
Faraday Rotation in Glasses
The Verdet constants of a number of glasses have been measured with the object of studying the Faraday effect in glass. The Verdet constant was measured for three types of glasses: (1) optical glasses, where the Verdet constant correlates well with the reciprocal dispersion; (2) diamagnetic glasses, where glasses whic…

Rapid method for the determination of cation‐exchange capacity of calcareous and non‐calcareous soils
Abstract “Compulsive” exchange takes place between a barium‐soil and magnesium sulphate solution because Ba 2+ ions are removed from solution by precipitation of barium sulphate. This phenomenon provides a basis for the very convenient routine method for cation‐exchange capacity determination in soils described here.…

Thermal Conductivity of Pure and Impure Silicon, Silicon Carbide, and Diamond
Thermal conductivity measurements on high-purity SiC and impure Si and SiC have been made over the temperature range from 3° to 300°K. These results show that the thermal conductivity K, of the highest purity SiC is intermediate between those of pure Si and pure diamond, and at 300°K is greater than that of copper. Th…

Rare-Earth Ions in the Alkali Halides. I. Emission Spectra ofSm2+-Vacancy Complex
Measurements have been made of the crystal-field splitting of the $^{7}F_{J}$ energy levels of the $4{f}^{6}$ configuration of the ${\mathrm{Sm}}^{2+}$ ion which is dissolved in a number of alkali-halide lattices. Crystal-field term assignments were made from the results of polarized-emission measurements. Observed cr…
Low-Temperature Recombination Luminescence in Alkali Halide Crystals
Luminescence observed upon low-temperature x-ray excitation of alkali-halide crystals has been identified as due to radiative electron-hole recombination in the perfect lattice. In KCl the emission spectrum is a single band, while in KBr, KI, and NaCl there are two bands. In crystals containing self-trapped holes, opt…
Kramers-Kronig Analysis of Reflectance Data for Diamond
The use of the Kramers-Kronig relation in the analysis of reflectance data is discussed briefly. The recent results of Walker and Osantowski for diamond are reanalyzed and found to be in some error. New data are presented which appear more consistent with the expected optical behavior of diamond.
